Tegami

Tegami (手紙, “letter”) is a small command-line tool for sending plain-text email from scripts and cron jobs without dragging in a heavy SDK.

The idea

Most notification libraries assume you want HTML, attachments, templating, and a vendor account. Sometimes you just want to send yourself a line when a backup finishes. Tegami does that — one binary, SMTP, no dependencies.

echo "nightly backup complete ✓" | tegami --to me@michi.sh --subject "backup ok"

What I learned

• Designing a CLI so the common case needs no flags and the rare case is still possible.
• How much friction a single static binary removes compared to “just pip install this.”
• That “boring and finished” beats “ambitious and abandoned” — a recurring michi theme.
